  • Best camping mattress we’ve ever used!
Color: Brown Size: Full Style: with Pump
This foam-filled air mattress completely changed our camping experience. It is extremely comfortable, well insulated, and surprisingly doesn’t sleep hot like some foam mattresses can. We woke up feeling like we had slept on a real bed rather than an air mattress. The biggest difference is the foam filling. It provides much better support and doesn’t have that “bouncy” feeling you get with a traditional inflatable mattress. The rechargeable pump is another huge plus. It inflates the mattress quickly and makes deflating it just as easy when it’s time to pack up. No struggling with a manual pump or trying to squeeze all the air out by hand. We use it in the back of our SUV, and it fits our setup perfectly. After sleeping on this, we will never go back to a traditional inflatable air mattress for camping. It’s comfortable, supportive, insulated, and incredibly convenient. If you’re looking for a comfortable car-camping mattress, I highly recommend this one. It’s worth every penny! ... show more

  • Affordable and comfortable
Color: Brown Size: Queen Style: with Pump
I initially wanted to purchase an Exped, but the price point was too high. This was at half the price plus you get a thicker mattress. My wife and I preferred using it with the least air and practically all foam, with both of us on the mattress the little air inside compressed enough to allow enough firmness for support and the foam gave enough cushion for a good night's sleep. It took 3 nights of camping to figure this out, but we know what we like on our next trip. It's easy to setup. Unpack and open the vent to allow it to self-inflate which takes less than 5 minutes, then adjust the air to your liking. High quality for sure!!! ... show more

  • Super comfortable, easy to set up. Game changer for camping.
Color: Brown Size: Full Style: with Pump
This thing was a game changer for us while camping. We used an air mattress for quite a number of years and had decent luck with it. However, once it gave up I did research and realized lots of people were recommending this mattress for camping. After our first weekend camping with it I can say it is amazing. It truly feels like a mattress you would have in your home. Crazy comfortable. No air loss. Great protection from the ground. I can't speak to it's long-term ability, but my first impression is incredibly high and I'm even considering purchasing a second (smaller version) one for my solo adventures. Also, the rechargeable pump that came with it is also amazing. It's tiny and works really well. For both inflating and deflating. ... show more

  • Extremely comfortable, easy to use
Color: Brown Size: Full Style: with Pump
It's an air mattress, but with foam layer on top. This makes it extremely comfortable - feels like a real mattress, not like an air mattress. The only downside is that the packed size is pretty big - but that's the price to pay for the comfort of the foam. Super easy to inflate/deflate with the pump. Solid well designed air intakes. If no pump, you can use the carry bag it comes with to inflate which is pretty cool. ... show more

  • Exactly what I needed.
This product is great! This was exactly what I needed for a better night's sleep. I use a cot when sleeping, and it was killing my lower back. I tried padding, I tried the 3" rollout memory foam I'd always wake up aching. This camping mattress was exactly what I needed. I was able to adjust it to as firm or soft as I needed it. It may cost a bit more, but it is worth the sanity of keeping myself comfortable. ... show more

  • Bad pump
Color: Brown Size: Queen Style: with Pump
I ordered the lost horizon mattress with the pump. The mattress itself is great. It’s really comfortable, but the pump that came with it quit working.

  • Great mattress but get a electric pump!
Very comfortable mattress. Used it in my apartment with guests and they liked it. Used it at a camping trip and it was nice not feeling the bumps on the ground. Slept well for the first time while camping! Only cons are that it takes awhile to fill up. Get the portable electric pump to speed this up. It is quite heavy but worth it. The carrier bag it comes with is really nice. I wish they included patches to repair emergency holes like other brands do but they didn't include any. I wish it was thicker as it's very low to the ground. ... show more
